How to call Badi - CRM_ORDERADM_H_MERGE only on saving of service request.

Question

Hello CRM Experts,
I am trying to change value of a field - "object_id" of table "CRMD_ORDERADM_H" while creation of a service request. I am doing this by implemeting BADI - CRM_ORDERADM_H_BADI, method - CRM_ORDERADM_H_MERGE. In this method I am creating a new number and updating it in Object_id field of orderadmh table. This badi is getting called on every button click like - NEW, SAVE, even on pressing enter in service request creation page.
But I want to execute the code written in this method only on clicking SAVE button in web ui. But I am not able to find a way to do so.
Please suggest something.
Thanks,
Pooja

Actually another way of doing this would be to create a new BTE function module instead.  You can control the timing so that the function module will only fire once upon save if you configure the correct event timing.
To find out more on how to use this do a search here on CRMV_EVENT or run that transaction code in your system and click on "read this information".
For a bigger hint you would target:
Transaction Category - BUS20001 - or specific category that you need.
Execution TIme - 78 Before Saving
Object - ORDERADM_H
Event - BEFORE_SAVE
Attribute <*>
or perhaps
Execution TIme 88
Object ORDERADM_H
Event - INIT
or even:
Execution time - immediately
Object ORDERADM_H
Event AFTER_Create
In either case the call callback would be of type C call  once per transaction
I would do an CRMV_EVENT_TRACE to figure out where to put this, but that's my best ideas.
Take care,
